Looking at
https://intel-gfx-ci.01.org/tree/intel-xe/xe-pw-146970v1/shard-bmg-2/dmesg15.txt,
I can see the following line:

  <7>[  432.399076] [IGT] kms_pipe_stress: finished subtest stress-xrgb8888-untiled, SUCCESS

Meaning that this test finished successfully. So this is probably some
coordination issue between CI and the test runner?

Similarly, the log in
https://intel-gfx-ci.01.org/tree/intel-xe/xe-pw-146970v1/shard-bmg-8/dmesg19.txt
contains:

  <7>[  358.222106] [IGT] kms_plane_lowres: finished subtest pipe-A-HDMI-A-3, SUCCESS

For this one, the final line of
https://intel-gfx-ci.01.org/tree/intel-xe/xe-pw-146970v1/shard-dg2-433/dmesg16.txt
seems to be the same as for the log presented in
https://intel-gfx-ci.01.org/tree/intel-xe/xe-pw-146970v1/shard-dg2-433/igt@kms_rotation_crc@multiplane-rotation-cropping-top.html.

That said, this should not be related to this patch, which is
non-functional and should be affecting other platforms as well if there
was an issue in the code update.

This seems to be the same as
https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/4278.
